UNDERCUTTING-SAW SUPPORT.

Specification of Letters Patent.

Application filed June 7, 1911.

Patented Jan. 30,1912.

Serial No. 631,793.

To all whom it may concern:

Be it known that I, JOHN B. PERRY, a citizen of the United States,residing at Meadowdale, in the county of Snohomish and State ofWashington, have invented certain new and useful Improvements inUndercutting-Saw Supports; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to saw supports for under cutting and has for anobject to provide a device attachable to an ax handle and which willsupport a saw while being moved upwardly in cutting.

A further object of the invention is to provide a saw supporting deviceattachable to an ax handle and adjustable to a variety of positions andpresenting a roller for engaging the back of a saw and supporting thesame.

With these and other objects in view the invention comprises certainnovel constructions, combinations and arrangement of parts as will behereinafter more fully clescribed and claimed.

In the drawings :Figure 1 is a view of the improved saw supportingdevice shown in operative position. Fig. 2 is a view of the device inend elevation. Fig. 3 is a view of the device in side elevation. Fig. 1is a vertical sectional view taken on line 44 of Fig. 3.

Like characters of reference indicate corresponding parts throughout theseveral views.

In the under cutting of logs and the like it is necessary to providemeans for supporting the saw as it is being used. The present inventionprovides a frame 10 having a hook 11 and a movable member 12 providingspace therebetween to receive an ax handle as 13 and a screw 14 forclamping the movable member 12 upon such handle. Upon the frame 10 aturn table member 15 is mounted by being pivoted centrally as by thepintle 16 so that said turn table member may rotate upon the frame 10.The turn table member 15 is provided upon opposite sides with inclinedportions 17 whereby the said member is provided at the center with anapex which serves as a fulcrum for the mounting of the tilting member18. The tilting member 18 is secured upon the turn table member by meansof a plurality of ears 19 which are carried by said tiltable member andfulorumed upon a pin 29 inserted through the turn table member adjacentthe apex. The pin also extends through the pintle member 16 and retainsthe same in position.

To provide for tilting the tiltable member screws 21 are providedextending through the said tiltablemember and into engage ment with theinclined surfaces 17. The tiltable member is also provided withupstanding ears 22 between which is journaled a roller 23 provided witha plurality of grooves 24 in which the saw 25 may be carried.

When starting the out in the under side of a log an ax is driven intothe log with the handle 18 disposed downwardly at an inclination. Thedevice is then attached to the handle, as indicated at Fig. 1, and theturn table rotated so that the axis of the roller 23 is substantiallyparallel with the axis of the log. This is accomplished not only byrotating the turn table member but by tilting the tiltable member untilsuch parallelism is accomplished. The saw is then inserted to be carriedin one of the grooves 24 and the cutting commenced. As the cuttingprogresses and it is necessary to raise the saw, the ax is withdrawnfrom the log and again driven in at a different angle or a differentposition to provide a change of position for the support.

I claim In an undercutting saw support, a frame, means to clamp theframe upon an ax handle, a turn table mounted to rotate upon the frameand provided with an elongated pivot, a tiltable member mounted to swingupon the pivot, screws carried one upon either side of the tiltablemember and adapted to control the inclination of such tiltable member,and a roller journaled upon the tiltable member.

In testimony whereof I aiflx my signature in presence of two witnesses.
